About this tool
CMYK is the colour model used in printing, where inks subtract light, while RGB is the model used on screens, where light is added. This tool converts a CMYK colour to its screen RGB channels and hex code. All four inputs must be percentages between 0 and 100. The conversion is a standard approximation, so a printed result can still differ from the screen colour because printers, paper and inks vary.
Frequently asked questions
What does K stand for in CMYK?
K stands for key, which is the black ink. It is called key rather than B to avoid confusion with blue.
Will the printed colour match the screen exactly?
Not necessarily. The conversion is an approximation, and real printers, paper and inks shift colours, so always proof important print work.
